PURIF YING ATTACHMENT FOR GAS-WELLS.

SPECIFICATION forming part of Letters Patent No. 560,783, dated May 26,1896.

Application filed March 28,1894. Serial No. 504,787. (No model.)

To all whom it may concern:

Be it known that I,FREDERIOK A.W. DAVIS, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in Gas-PurifyingAttachments for Gas-Wells, of which the following is a specification.

The object of my said invention is to produce a device by which naturalgas after it emerges from the wells may be purified, or separated fromthe fine particles of carbon, dirt, and other substances which otherwisemay be driven into the gas-mains, and also from time to time to cleanout or discharge these impurities from the apparatus.

An apparatus embodying my said invention will be first fully described,and the novel features thereof then pointed out in the claim.

Referring to the accompanying drawings, which are made a part hereof,and on which similar letters of reference indicate similar parts, Figure1 is an elevation of a pipe emerging from a gas-well, with my improvedseparating apparatus interposed between the well and the gas pipe ormain which leads off therefrom; Fig. 2, ahorizontal sectional viewacross the purifying apparatus, on the dotted line 2 2 in Fig. 1, on anenlarged scale; and Fig. 3, an end view of said apparatus as seen fromthe dotted line 3 3.

In said drawings the portions marked A represent the pipe coming up outof the ground and forming the upper end of the well; B, the casing of myimproved purifying apparatus; 0, the filter in said casing, and D thegas pipe or main leading off from the purifying apparatus.

The pipe A is the ordinary well-pipe as it appears extending above thesurface of the ground where the well is driven. Such a pipe is usuallyprovided with a gage or indicator A to show the pressure of gas, and hasa cap A from which a continuation-pipe A leads to the off-going gas pipeor main in ordinary cases, but when my purifying apparatus is used leadsthereto. In this pipe A at a suitable point, is a valve A by which theflow of gas from the well can be shut off when desired.

The purifying apparatus consists of the I casing 13, having heads B andB in its ends,

and is provided with a blow-off pipe B The pipe A, leading from thewell, enters this casin g at an appropriate point on one side of thefilter, and the cit-going gas pipe or main D connects therewith atanother appropriate point on the other side of the filter, as shown.

The filter 0 consists of a cage with perforated ends, and filled withsome suitable filtering material adapted to intercept any particles ofcarbon, dirt, or other matter with which the gas may be mixed as itemerges from the well, while permitting the free passage of purifiedgas. This filter is positioned at an appropriate point between the pipesA and D, and is held in place by means of rods 0 and G which passthrough the heads B and B of the casing B and bear against the ends ofthe cage of the filter O. Said rods are also screw-threaded, so thatthey may be adjusted as desired.

The off-going gas pipe or main D is of the usual character, and isprovided with a valve D.

The operation is as follows: The gas upon emerging from the wellisdischarged into the lower portion of the purifying. apparatus, whenthe dirt, carbon, 820., is intercepted by the filter, and will drop tothe bottom of the chamber in said apparatus, while the gas passes on andgoes into the main D,as isusual. Dampness may also collect in thispurifying apparatus and settle to the bottom together with the dirt.When the apparatus needs cleaning, it is readily done by closing thevalve A and opening the valve 11 in the discharge-pipe B when thepressure of the gas in the main D will be suificient to blow out thematter collectedin the bottom of the purifying apparatus. If anysubstance collects upon the sides of the interior of this apparatus, itmay be removed by shutting both the valves A and D, taking out the headsB and I3 and pushing the filter O through the apparatus from end to end,which will obviously clean it out fully and efiectively.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is-

The combination, with a gas-well, of a pipe ICO provided with anappropriate valve connected thereto above said filter, and a blow offpipe With suitable valve connected to said apparatus near the bottom ofthe casing, all substantially as described and for the purposesspecified.

In Witness whereof I have hereunto set my hand and seal, atIndianapolis, Indiana, this 19th day of March, A. D. 1894.
